Title: Memory read and write method and device
Inventor: OSHIMA YASUHISA
IPC: G06F21/62
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To prevent an outsider from analyzing the program stored in a memory and also transforming wrong the program by switching a bus to a pattern different from the normal one when a CPU writes the data into the memory and switching again the bus to the normal pattern when the CPU reads the data out of the memory. SOLUTION: The scramble value is set to a data scramble/descramble circuit 5 and an address scramble circuit 6 which are contained in a scramble circuit 7. Thus, a data bus DB and an address bus AB are partly scrambled and connected to a data terminal DT and an address terminal AD of an SRAM 3 or a flash memory 4 as a scramble data bus SQDB and a scramble address bus SQAB respectively. A CPU 1 writes the scramble value into a non-scramble area of the memory 4. Then the CPU 1 copies an application program of the SRAM 3 to the memory 4.

Abstract: PROBLEM TO BE SOLVED: To improve the adhesion of a lead frame for semiconductor device with an adhesive and a sealing resin and, in addition, the wire bondability and solder wettability of the lead frame. SOLUTION: Firstly, a lead frame member 10 having the shape required for a lead frame for semiconductor device is formed from a metallic belt-like material. Then Pd-plated layers 12 are formed on both surfaces of the member 10 directly or through plated base layers 11. After the layers 12 are formed, plated layers of a heat-resistant precious metal are formed on the layer 12. Then the Pd in the layers 12 is diffused in the layers 13 by heat-treating the member 10 carrying the layers 12 and 13 in a diffusion furnace maintained in a vacuum of nonoxidative atmosphere. After the Pd is diffused, the Pd diffused in the surface zones of the layers 13 are oxidized by again heat-treating the member 10 in a furnace maintained in an oxidative atmosphere.

Title: Device for recording and reproducing digital video signal
Inventor: TEJIMA OSAMU
IPC: H04N7/081
Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To reduce a transmission line in the internal processing of auxiliary data signals in a digital video/sound signal recording and reproducing device, which records and reproduces the auxiliary data signals accompanying digital video signals. SOLUTION: An auxiliary data detection conversion circuit 14 detects an auxiliary data signal from an input digital signal SI2 and makes the signal an intermediate type auxiliary data signal. A signal mixing circuit 13 superimposes the auxiliary data signal in a period, corresponding to the horizontal blanking period of a digital video main signal. In this way, because the internal signal S9 of a video signal and the internal signal S10 of the auxiliary data signal to be recorded can be made the same transmission signal S11, a transmission line where the auxiliary data signal is separately transmitted can be eliminated.

Abstract: PURPOSE:To provide improved response by releasing the travel driving force of a mobile carriage to return it by the action of the spring accumulated during traveling when a recovering roller on a self-running carriage comes in rotational contact with the cloth free-edge portion of an original cloth roll and receives a given frictional force. CONSTITUTION:When an original cloth roll 9 is rotated and supported on in clined belt conveyers 11, 12 and a free-edge portion Te is at an opposing posi tion to a recovering roller 16, an undetected mark K formed beforehand on a cloth surface is detected by a sensor S1 to stop the rotation of the roll 9, drive motors M1, M3, rotate the roll 16 in the resuming direction and make a mobile carriage 15 run to the side of the roll 9. At this time, a torsion spring 30 is energized during traveling and the roller 16 comes in contact with the roll 9 for resuming, and when friction force increases apart from the free-edge portion Te, this is detected by a limit switch LS to release driving of the motor M3 and return the mobile carriage 15 by an energizing force of the torsion spring 30.

Title: Digital signal decoding device
Inventor: OKAMOTO HIROO
IPC: G11B20/14
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To decode excellently a compressed video signal by stopping synchronization of a clock by a PLL at a variable speed reproducing time. SOLUTION: When a digital signal recording/reproducing device is reproduced, a packet selection circuit 601 decodes an input regenerative signal to an input terminal 606b to video and audio signals by the same operation as the time at a receiving time. A PLL circuit 603 generates a master clock of a decoding circuit with reproducing program clock reference information to decode synchronized with the master clock of the device. However, as the variable speed reproducing data, record of program clock reference information for reducing a data amount doesn't exist. Further, even when it exists, since the data are reproduced at a speed different from usually, a program reference information value doesn't coincide with a real time. Then, at the variable speed reproducing time, PLL control is stopped with a control signal inputted to the input terminal 607 to output a fixed clock.  That is, at the variable speed reproducing time, time control is eliminated, and an input packet as it is is outputted.
